Default Stupid DC motor control question

I have this perfect Bodine 130v DC gearmotor, except that it's blue,
courtesy of Gunner, for a project. (SEE: one-way clutch) I just got a
Dart
Controls control for it on eBay for $26. It puts out 90 or 180 volts
with a
115-230 vac input.

Stupid question: (Children should leave the room)

Can I use 2 legs of my 3-phase to power it?


Yes, assuming you're talking about 240V 3 phase, but the controller will
exceed the motor's nameplate at top speed. The control may have a high
speed limit adjustment that will take care of that.

The 130VDC motors that Bodine builds are unusual. If you use a typical
controller powered by 120VAC the motor won't reach full nameplate speed.
Bodine makes controllers with filtered outputs that will drive their
motors to full speed.

Wow, I thought for sure I was going to get lambasted. I don't need the top
speed of 38 rpm, I want about half that. Now I can just tuck the controller
in the spacious 3-phase box.
